When the dice is rolled 14 times then from the given data the probability of 1,2,3,4,5,6 is 3/14,1/14,4/14,1/14,3/14,2,14.

Given Roll of dice and outcomes from 1 to 14 is 1,3,5,4,5,3,3,1,3,5,6,1,6,2.

From the given collected data we can find out number of times each number came when the dice is rolled.

Number of times 1 came=3

Number of times 2 came=1

Number of times 3 came=4

Number of times 4 came=1

Number of times 5 came=3

Number of times 6 came=2

The probabilities are in fraction form:

P(1)=3/14

P(2)=1/14

P(3)=4/14

P(4)=1/14

P(5)=3/14

P(6)=2/14

The probabilities in decimal form:

P(1)=0.21

P(2)=0.07

P(3)=0.28

P(4)=0.07

P(5)=0.21

P(6)=0.14

The probabilities in percentage:

P(1)=21%

P(2)=7%

P(3)=28%

P(4)=7%

P(5)=21%

P(6)=14%

Hence the probabilities are 3/14,1/14,4/14,1/14,3/14,2,14.

What is the image of the point (2, -3) after a rotation of 180° counterclockwise

horsena [70]

Answer:

(-2, 3)

Step-by-step explanation:

When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative

Point (2, -3) becomes:

Point (-2, 3)

Answer:

(1).(C) Commutative property.

(4).(D) 3

(3).(D) 75

Step-by-step explanation:

(1) Commutative property of addition states that if two number p and q are real. Then, it doesn't matter in which order the numbers are added it will provide the same result. i.e.

p + q = q + p

Therefore, -8 + (-15) = (-15) + (-8) is an example of commutative property.

(2) - (q+14) = (-3) + (-14)

$\Rightarrow -q - 14=-3 -14$

$\Rightarrow-q= -17 +14$

$\Rightarrow-q=-3$

$\Rightarrow q=3$

(3) -10 + a + (-15) = 50

$\Rightarrow a -25 = 50$

$\Rightarrow a = 50 + 25 = 75$
